SAN FRANCISCO -- There are no guarantees at the Super Bowl.
Great franchises (Pittsburgh Steelers) have lost there. Great teams (2007 New England Patriots) have lost there. Great offenses (2001 St. Louis Rams) have lost there. Great quarterbacks have lost there: Roger Staubach, Dan Marino, John Elway, Jim Kelly, Brett Favre, Tom Brady and Peyton Manning. So have the great coaches: Don Shula, Tom Landry, Joe Gibbs and Bill Belichick.
But when a great defense shows up, it generally doesn't lose.
And the Denver Broncos are bringing a great defense to Super Bowl 50.
The Broncos bring the NFL's best defense to Sunday's game against the NFC champion Carolina Panthers.
